SPECIALIZED MEASUREMENTS WITH THE HI-
3603

This section is intended for those individuals wishing to obtain
more detailed information on the characteristics of VDT
emissions than might normally be considered routine.

FLYBACK FREQUENCY MEASUREMENTS

The HI-3603 is equipped with a waveform output jack located on
the bottom of the case which provides a signal from the
preamplifier in the input module. This is an analog signal that has
essentially the same shape as that of the electric or magnetic
field waveform that is being measured. Connection of a
